7 tips for choosing a wireless antenna

Whether the wirelessnetwork adapter,wirelessAP orthewirelessrouter,built-inwirelessantenna.Therefore,when the distanceisclose,usersdo not need toinstallan externalwirelessantenna.However,when the distanceexceeds20~30metresofindoorandoutdoortransmissiondistanceexceeds50~100metres,it is necessary to considerinstallingan externalantennafor the wirelessAP or the wirelessnetwork adapter in order to enhance the wirelesssignalstrength,extendscoverage for your wirelessnetwork.

Morevarietiesofwirelesscommunicationantennas in XI ' an, in order tomeettherequirements of differentfrequencies for differentpurposesanddifferentoccasions,therefore,whenpurchasingantenna, it should benoted the followingfactors:

Wirelessstandards

At present, the availablewirelessnetworksthere are3maincriteria,namely, IEEE 802.11b,IEEE 802.11gandIEEE 802.11A.Among them,IEEE 802.11b,IEEE 802.11gworking2.4GHz andIEEE 802.11Aworking5GHz.Wirelessproductsshould beusedwith the implementation of the standardscorresponding to the wirelessantenna.

Applicationenvironment

Whenlongdistancecommunicationisneeded,somewirelessAP and the wirelessrouter'santennasare in the Interior,whileothersarelocated inan outdoor,therefore,shouldchooseindoorantennaoran outdoorantennasuitable for differentenvironments.Need to be awareofisthatindoorantennanowaterproofandmine,so,indoorantennasmustnotbeusedoutdoors.

Coverage

When the needforlong-distancedata transmission,shouldchoose the biggainof the antenna,andforproximitywirelessnetwork,you canselect a smallantenna.Typically,largeantennasuitable forlong-distancetransmission,while the small-gainantennaissuitable for networkroamingand otherapplications that requirelargecoverage.GainusesdBi indoorantennaare4~5dBi,outdoorantennasare mostly8.5~14dBi.

Connecteddevices

Directional antennadirectivityis verystrong,canfocus the signalsendtoorreceivefromonedirection in onedirection.Omni-directional antennascan beOmni-directionalsendorreceiveradiosignalscancover a verywide rangeofareas,buteverydirectionsignalisweak.So,typically,Omni-directional antennashould I choose the wirelessAP and the wirelessrouter,andwirelessnetwork cardyoucanuse a directionalantenna.

Networktype

For a peernetwork,wirelessnetwork adaptershould beused in allOmni-directionalantenna.Ifonlytwowirelessnetwork cardwirelessnetwork,then,naturally, shouldall be usingdirectionalantennas.

Networksfor the accesspoint,wirelessAP orwirelessrouterrequiredforwirelessnetworkin the wirelessnetwork adapterprovideswirelessconnectivity and,therefore,shouldchoose a Omni-directional antenna.Andas the wirelesscard,onlyneed to communicatewith a wirelessAP orwirelessrouter,so a directionalantennashould Ichoose.

Installationlocation

Althoughsomeindoorantennascan beinstalledon a desktopormountedon a wall.However,someproducts are onlysuitable fordesktop.Shouldtherefore be based on the locationof your wirelessAP orwirelessrouterinstallation,determine the appropriatetypeofindoorantenna.

Productbrands

Althoughwirelessproductsfollow the samestandards,however,usedifferentproductstend to have a differentinterface,differentcables,sodifferentbrandsofwirelessantennasare oftennotgeneric.
